Answer 2

Answer:

Least number must be subtracted from 178 to make it a perfect square number is 9.

Step-by-step explanation:

Here given digit is 178.

We want to find least number must be subtracted from 178 to make it a perfect square number.

For solving this question,we need to remember Square value of some digit.

List of square values upto 30:

${1}^{2} = 1 \\ {2}^{2} = 4 \\ {3}^{2} = 9 \\ {4}^{2} = 16 \\ {5}^{2} = 25 \\ {6}^{2} = 36 \\ {7}^{2} = 49 \\ {8}^{2} = 64 \\ {9}^{2} = 81 \\ {10}^{2} = 100 \\ {11}^{2} = 121 \\ {12}^{2} = 144 \\ {13}^{2} = 169 \\ {14}^{2} = 196 \\ {15}^{2} = 225 \\ {16}^{2} = 256 \\ {17}^{2} = 289 \\ {18}^{2} = 324 \\ {19}^{2} = 361 \\ {20}^{2} = 400 \\ {21}^{2} = 441 \\ {22}^{2} = 484 \\ {23}^{2} = 529 \\ {24}^{2} = 576 \\ {25}^{2} = 625 \\ {27}^{2} = 729 \\ {28}^{2} = 784 \\ {29}^{2} = 841 \\ {30}^{2} = 900$

Here 178 is nearest value of 169 which is square value of 13.

So if we will substract 169 from 178 then we will get least number must be subtracted from 178 to make it a perfect square number.

Therefore,$(178 - 169) = 9$is least number must be subtracted from 178 to make it a perfect square number.
